Role of Neuroimaging Before Coronary Angiography in Patients With Out-of-Hospital Cardiac Arrest.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatients presenting following out-of-hospital cardiac arrest (OOHCA) often require emergency coronary angiography. Presentations can be associated with syncope or head-trauma.
aimsWe investigated the impact and utility of pre-coronary angiography CT-Brain (CT-B) in patients following OOHCA on clinical outcomes.
methodsRetrospective analysis was undertaken at a large metropolitan hospital to identify patients. Patients following OOHCA who were transferred directly to the cardiac catheterization lab were included with patients stratified according to whether they received a CT-B prior to coronary angiography or not.
resultsFollowing analysis, 235 patients met inclusion criteria. The CT-B (n = 39) and non-CT-B (n = 196) groups were similar in baseline demographics with respect to age (64.1 vs. 63.3 years, p = 0.739), male sex (79.2% vs. 82.7%, p = 0.637), hypertension (48.7% vs. 49.2%, p = 0.953), and hypercholesterolemia (33.3% vs. 32.8%, p = 0.950) respectively. There was no difference in ECGs suggestive of cardiac ischemia (53.8% vs. 61.7%, p = 0.338). The CT-B group were more likely to have fallen (89.7% vs. 50.5%, p < 0.001), and have documented head strike (61.5% vs. 8.2%, p < 0.001). Door-to-procedure time was significantly longer in the CT-B group (105 vs. 53 min, p < 0.001). There was no difference in length of ICU stay (median 3 (IQR 1-6) vs. 3-days (IQR 1-6), p = 0.44), or 30-day mortality (41.0% vs. 29.5%, p = 0.159). Of those undergoing CT-B, 17.9% had pathology identified, with only one patient (2.6%) having their angiogram deferred.
conclusionIn patients with OOHCA, pre-angiography CT-B has a low likelihood of identifying neuropathology and significantly increases DTP time.
